Question:

(a) Cyanic acid (H-O-C≡N) and isocyanic acid (H-N==C==O) differ in the positions of their electrons but their structures do not represent resonance structures. Explain.
(b) Loss of a proton from cyanic acid yields the same anion as that obtained by loss of a proton from isocyanic acid. Explain.
